Title: Junichi Tsuchiya: Innovator in Perforation Technology
Introduction
Junichi Tsuchiya is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of perforation technology, holding a total of six patents. His work primarily focuses on creating innovative solutions for film processing.
Latest Patents
One of Tsuchiya's latest patents is a perforator designed for making perforations in a continuous film. This film is subsequently cut into individual filmstrips of variable lengths. The perforator features a die set unit that includes multiple punches and corresponding dies arranged along the continuous film. The die set unit performs die-punching N times in each first section of variable length Lx. A measuring feeder transports the continuous film by a first length after each of the (N-1) die-punching actions and by a second length after the final die-punching for every first section. The first length is calculated as Lx/N, while the second length corresponds to the first length plus the length L2 of a second section that alternates with the first section along the film. Additionally, the die set unit consists of first to nth die sets aligned in order from downstream to upstream in the film transporting direction. Each die set has a specific number of punches, and the first to ith die sets are activated simultaneously to perform die-punching based on the number of frame exposure locations required in each individual filmstrip.
